COMPOSITION-FACED BUTTON.

SPECIFICATION forming part of Letters Patent No. 395,186, dated December25, 1888.

Application filed October 15, 1888. Serial No. 288,154. (No specimens.)

T aZZ whom, it may concern.-

Be it known that I, ISAAC SMITH, of Brooklyn, in the county of Kings andState of New York, have invented a new Improvement in Composition-FacedButtons; and I do hereby declare the following, when taken in connectionwith accompanying drawing-sand the letters of reference marked thereon,to be aful, clear, and exact description of the same, and

which said drawings constitute part of this specification, andrepresent, in

Figure 1, an edge view half in section; Fig. 2, a section representingthe introduction of the back into the front; Fig. 3, an edge View I 5half in section of the metal blank for the front,

detached. 5

This invention relates to an improvement in the manufacture of buttonsin which the body is metal, but the exposed surface covered with acomposition or non-metallic material applied to the blank in a plasticcondition, and is an improvement upon the invention for which LettersPatent of the United States No. 381,at38 were granted to me April In myprevious patent the blank for the face of the button was of cup shape,made from sheet metal, and substantially the same as that employed forcloth faced buttons, ex-

3 cept that the blank was perforated with numerous holes, and so that aplastic composition applied to the face of the blank would be forcedthrough the holes in the blank and become interlocked therewith, so thata very 3 5 thin coating of composition could be employed, and yet insureits secure attachment to the metal blank. The flange or the side of thecap was left uncoated and closed over the back in the usual manner forclosing the faceblank over the back in cloth buttons. This under theordinary construction of. buttons leaves the side of the cup or frontexposed uncoated,because the coatiu could only extend to the point wherethe bend was to be made in the side of the cup in closing it upon theback.

The object of my present invention is to so construct the front and backthat the blank for the front may be wholly covered-that is to say, sothat the bending of the flange or side of the cup may be avoided,thereby enabling the blank for the front to be covered on its faceentirely over its sides.

To this end my invention consists in constructing the blank for thefront with its flange or side turned inward-that is, contracted-and witha concentric rib upon the inside of the cup adjacent to the inclinedflange, and a cup-shaped blank for the back, its external diametercorresponding to the contracted diameter of the flange of the front, andso that as the back is forced into the front its edge will strike thesaid rib and be deflected outward between the said rib and the inclinedflange of the front, whereby the back and front will be firmlyinterlocked and as more fully hereinafter described.

In Fig. 3 the blank for the front is shown in half transverse sectiondetached and without the covering. It is made from sheet metal struckinto cup shape, and the side or flange (4 turned back from the front andinward, so that the internal diameter of the flange at its edge is lessthan the internal diameter of the blank in the plane of the front. Inthe front and adjacent to the side of the blank an illternal rib, b, isformed substantially around the blank and concentric to the flange a, asclearly seen in Fig. 3. This rib leaves a space,

(I, between it and the surrounding flange a, the adjacent surfaces ofthe flange and of the rib being inclined inward, as shown. The rib l) isbest formed by making a circular depression in the face of the button.The blank for the front is perforated, as in my previous patent, and theblank is covered with the plastic material 6, as seen in Fig. 2, the material extending over the edge and so as to cover the flange or side ofthe front, as shown. The application of the plastic material to the 0back is best made substantially in the same manner as described in myprevious patent, and not necessary to be described in this applicationfurther than to say that suitable dies are provided by which therequisite p ressure is applied to the plastic material to bring it tothe required shape, and at the same time to cause it to enter theperforations in the front, wherebyit will securely interlock therewith.The back f is made from sheet metal, of cup shape. The external diameterof the side or flange 9 corresponds to the internal. diameter of theouter edge of the flange a of the front, and so that the back may be setinto the front, the flange inward, as seen in Fig. 2. The flange g ofthe back strikes the outwardlyinclined surface of the rib b in thefront, and, suitable force being applied, the flange of the back isdeflected over the rib 1) into the space between the said rib and theflange a on the front, as seen in Fig. 1, and so that the back is firmlyinterlocked with the front. The depth of the back should be such as topermit it to be entirelyinclosed within the front, as represented inFig. 1, or substantially so. Under this construction I am enabled tocover the entire surface of the front, because in the closing of theback and front together there is no bending effect produced upon thefront or any part of it; hence no disturbance of the coating.

I do not claim, broadly, a button having an under-cut groove in itsfront portion, with a ring-shaped disk inserted into this under-cutrecess, and so as to hold the eye portion in place, as such I am awareis not new.

It will be understood that I claim nothing in this application shown ordescribed in my before-mentioned patent; but

WVhat I do claim, and desire to secure by Letters Patent, is

The herein-described improvement in composition-faced buttons, whichconsists in a metal cup-shaped blank for the front, constructed with itsside orflange turned inward, so that the inner surface is inwardlyinclined from the plane of the front, and the front also constructedwith a concentric rib upon its inside adjacent to its flange andcorrespondingly inclined, the outer surface of the blank covered with acomposition, the said composition extending over onto the inclined outersurface of the flange and so as to cover that surface, combined with acup-shaped back, the external diameter of the flange or sidecorresponding to the internal diameter of the flange of the front at itsouter edge and forced into the front against the inclined surface of thesaid rib, and thereby deflected outward between the said rib and theside of the front, whereby the said back is interlocked with the front,substantially as described.
